Linking two columns so time changes are mirrored

[SteveS128]

Hi All!
I am creating an excel spreadsheet for an event


There are two time columns side by side in the same sheet.


One shows ‘time code’ (like what is used for film) and the other shows ‘track time’ (which shows how long that particular track has been going)


So for example, for the third ‘segment’ of the show, the timecode will show
03:00:00 (to indicate we are starting section 3)


And the track time will show
00:00:00 (as this track is at it’s beginning)


As the timecode progresses, the track time elapses at the same rate.


So, once we get up to 03:01:25 for example,
The track time will show 00:01:25


My question is -


Is there a way to link these two columns so if I make a change to the time code (lets say I changed the track time cell from 00:01:25 to 00:01:27), that the ‘track time’ will update also to show 00:01:27, without me having to manually edit both cells.


As you’ll see, the MM:SS parts of the time will reflect each other
But I want the HH time to be independent


Furthermore, sometimes the ‘timecode’ will be something like
03:30:00
and track time would reset to 00:00:00


So it’s not as simple as just mirroring mm:ss only as sometimes the mm column will be 30 or 50


I guess I’m looking for a code that means that if I add or subtract time to one side, it will do the same on the other


Hope that makes sense!


I am using Excel for Mac 2011


Thanks in advance,
Steve
